It can be placed on any flat surface 2 blocks wide. Though it is normally only 2 blocks tall, it requires an extra 2x2 clear space above it to expand when opened. It does not provide a stacking surface.

It casts a dim red ambient light that cuts through roughly 2 layers of foreground blocks. The light level stays the same when the chest is opened despite the extra glowing real estate. When read by a newly-placed Colony Deed, the Chest will count towards a Tier-4 Guard Tenant.

Though this item was added to the game files in the major "Rampaging Koala" Beta development update that brought the game very close to its "final" state, it has never actually been implemented in the game proper.
